V2: - Rebase on latest next/master
V3: - Add vendor specific compatible for the platform
    - Rename ledgrp and touchscreen nodes to follow DT spec
    - Update pinmux (LVDS has no pin config, so use default settings)

Doesn't this need adding to
Documentation/devicetree/bindings/arm/fsl.yaml ?

Yes, missed that.

Marek,

Please send an incremental patch for that.  Thanks.

Please move the regulator outside the 'simple-bus':

reg_usbh1_vbus: regulator-usbh1-vbus {

The 'reg' property can also be removed.

The GPIO flag 0 means active high, but since you are not passing
'enable-active-high' this should be:

 gpio = <&gpio1 2 GPIO_ACTIVE_LOW>;

> +&i2c2 {
> +       stmpe610@41 {

Node name should be generic, so:

touchscreen@41

There is an @0 without a corresponding reg property. This triggers a
dtc warning when building with W=1.

Please fix it.
